shot on dribbble:

The iPhone mockup available here.

• iOS 8.0+
• Xcode 7.3

Just add the Source folder to your project.

or use CocoaPods with Podfile:

pod 'expanding-collection', '~> 0.0.2'

import expanding_collection

1. Create UICollectionViewCell inherit from BasePageCollectionCell (recommend create cell with xib file)

2. Adding FrontView

• add a view to YOUCELL.xib and connect it to @IBOutlet weak var frontContainerView: UIView!
• add width, height, centerX and centerY constraints (width and height constranints must equal cellSize)

• connect centerY constraint to @IBOutlet weak var frontConstraintY: NSLayoutConstraint!
• add any desired uiviews to frontView

3. Adding BackView

• repeat step 3 (connect outlets to @IBOutlet weak var backContainerView: UIView!, @IBOutlet weak var backConstraintY: NSLayoutConstraint!)

4. Cell example DemoCell

1. Create a UIViewController inheriting from ExpandingViewController

2. Register Cell and set Cell size:

override func viewDidLoad() {
    itemSize = CGSize(width: 214, height: 264)
    super.viewDidLoad()

    // register cell
    let nib = UINib(nibName: "CellIdentifier", bundle: nil)
    collectionView?.registerNib(nib, forCellWithReuseIdentifier: String(DemoCollectionViewCell))
}

3. Add UICollectionViewDataSource methods

extension YourViewController {

  override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return items.count
  }

  override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("CellIdentifier"), forIndexPath: indexPath)
    // configure cell
    return cell
  }
}

4. Open Cell animation

override func viewDidLoad() { itemSize = CGSize(width: 214, height: 264) super.viewDidLoad()

// register cell
let nib = UINib(nibName: "CellIdentifier", bundle: nil)
collectionView?.registerNib(nib, forCellWithReuseIdentifier: String(DemoCollectionViewCell))

}

  func collectionView(collectionView: UICollectionView, didSelectItemAtIndexPath indexPath: NSIndexPath) {

      cell.cellIsOpen(!cell.isOpened)
    }

1. Create a UITableViewController inheriting from ExpandingTableViewController

2. Set header height default 236

override func viewDidLoad() {
    super.viewDidLoad()
    headerHeight = ***
}  

3. Call the push method in YourViewController to YourTableViewController

  if cell.isOpened == true {
    let vc: YourTableViewController = // ... create view controller  
    pushToViewController(vc)
  }

4. For back transition use popTransitionAnimation()
